Andreas Pehrson 2feaa6b104 Bug 1334421 - Don't use templated class for refcount macros in MediaParent. r=jib
The assert in bug 1334421 mentions the MOZ_COUNT_{C|D}TOR macros, but the same
comment seems to apply to the NS_LogAddRef that's part of the
NS_INLINE_DECL_THREADSAFE_REFCOUNTING macro.

This fixes it for me.
